Abstract: A fuel injection pump for internal combustion engines having a supply quantity adjusting device, in which a full-load stop for the quantity adjustment can be varied by the imposition of a stepping motor, and in which idling rpm governing is possible. The adjusting device has a tensed drag lever group, which acts as the stop lever for the stepping motor. If the stepping motor should fail in the idling position, emergency operation is possible by overpressing the drag lever.

Abstract: A device for injecting a fuel-gas mixture having a cup-shaped gas enveloping sleeve in which the cylindrical part of the gas enveloping sleeve permits exact centering of the gas enveloping sleeve relative to the fuel injection valve. The novel device while having very exact centering of the gas enveloping sleeve relative to the fuel injection valve has the advantage of a simple, economical manufacture. The device includes radially inwardly pointing guide strips that rest with their face ends on the circumference of the fuel injection valve and thus in a simple way center the gas enveloping sleeve relative to the fuel injection valve. The device for injecting a fuel-gas mixture is especially well-suited for injection of a fuel gas mixture into the intake tube of a mixture-compressing internal combustion engine with externally supplied ignition.

Abstract: The protective cap for a fuel injection valve having a recess which extends radially outwards from a through flow passage, this recess being so small that it has a capillary effect on the fuel, so that when the internal combustion engine is stopped, the fuel constituents which boil at high temperatures are deposited on the radially outer edge of the recess, due the capillary action, and the injection orifice of the fuel injection valve remains free of deposits. The protective cap can be used for different types of fuel injection valves.

Abstract: A fuel injection device for fuel-injected internal combustion engines, in particular to a unit fuel injector, in which the control of the onset and end of supply is effected by means of a magnet valve incorporated between a low-pressure circuit and a work chamber of a pump piston; a scavenging bore, connectable to the work chamber, of a scavenging line that communicates with a low-pressure chamber or the tank is provided. A delivery line for delivering the fuel from the magnet valve to the work chamber of the pump piston discharges directly into the pump work chamber and communicates with it in a permanently open fashion.

Abstract: An apparatus for injecting a fuel-gas mixture into the mixing lines of a mixing housing, so that a maximally homogeneous fuel-gas mixture is assured. The fuel is injected in an oriented fashion for the injection ports directly into the mixing lines in an accurate fuel distribution to the various mixing lines in a maximally homogenous mixture formation. From a central gas delivery line, the gas reaches each mixing line via a respective gas conduit. Via the mixture injection lines, the mixture is delivered to the cylinders or injection groups of an internal combustion engine.

Abstract: A fuel injection pump for internal combustion engines with a load- and/or rpm-dependent injection course formed by a reciprocating fuel control slide and a piston pump. The piston includes oppositely disposed slits and the reciprocating control slide has a graduated recess on its lower edge oriented toward the pump piston control slits, or the lower edges of the control slits are given a suitable geometry for fuel control.

Abstract: A pressure limiting valve has a valve closing member (ball), which is subjected to a hydraulic opening force and is indirectly subjected to a closing force generated by a compression spring which avoids hysteresis that impairs the switching behavior of the pressure limiting valve. A tappet, which passes through a sealing ring and is exposed to a control pressure, is also capable of acting in a closing manner upon the pressure limiting valve. When there is no operative control pressure, the tappet is pushed back by the opening of the pressure limiting valve and is retained in this position by frictional forces brought about by a sealing ring. The switching plays of the pressure limiting valve are free of frictional forces. The pressure limiting valve is suitable for use in hydraulic motor vehicle brake systems.

Abstract: A novel fuel injection valve including an armature which has a through bore, which communicates with a blind bore formed concentrically with a longitudinal valve axis in a ball serving as the valve closing body, and at least one transverse conduit begins at this blind bore and extends to an outer surface of the ball. The fuel reaches the valve seat through the through bore, the blind bore and the at least one transverse conduit. This results in an especially compact embodiment of the fuel injection valve according to the invention. The fuel injection valve is especially well-suited to fuel injection systems of mixture-compressing internal combustion engines with externally supplied ignition.

A continuous band comprises a plurality of the wire-identifying tabs which are connected together by joining portions so that the band is fed continuously to the apparatus.

Abstract: A fuel injection pump for internal combustion engines having a fuel injection quantity adjusting device, in which by the imposition of a stepping motor and by varying a spring assembly at the adjusting device, not only can the starting and full-load injection quantities be controlled but the idling injection quantity can also be regulated as a function of engine operating parameters.

Abstract: A magnet system for an outwardly opening magnet valve having a core winding, an armature carrying the valve body, and a permanent magnet disposed symmetrically to the winding. The closed magnet circuits of the electromagnet and permanent magnet partly overlap, and a ring of ferromagnetic material is associated with the permanent magnet 1 in the magnet circuit of the electromagnet, this ring absorbs half the flux I of the permanent magnet, and the magnet circuit for the electromagnet is dimensioned to one-half the permanent flux.

Abstract: The invention is based on a fuel injection pump in which to supply a very rapid pressure rise in the interior of a fuel injection pump, a pressure valve controlling this pressure is modified such that upon cold starting of the engine, the pressure valve closes a bypass line at the feed pump and thus delivers all the fuel to the fuel injection pump. The closure is effected as a function of rpm and accordingly pressure, and also as a function of the engine operating temperature; in the fuel injection pump according to the invention, the rpm- and pressure-dependent diversion is performed by the adjusting piston of an injection adjuster. Thus, compared with the known cold-starting accelerating devices, one additional pressure limiting valve can be eliminated.
